Note that while this method saves memory and improves performance it is a step to a lower abstraction
layer and you will loose some features that the active record layer has.
Fetching data using asArray is nearly equal to running a normal query using the [query builder](db-dao.md).
When using asArray the result will be returned just as such a query and no typecasting is performed anymore
so the result may contain string values for fields that are integer when accessed on the active record object.
